– A USB DVB-T/DAB stick TV receiver, only equipped RTL2832 and tuner R820T (avoid usb stick with E4000 tuner for ADS-B) Yes, it is an initiative of the Air Traffic Organization (ATO ) of the Federal Aviation Administration (FAA) of the United States, who encouraged it under the NextGen project : Next Generation Air Transportation System.

The frequencies range are from 118MHz to 136MHz in AM (amplitude modulation) for less than 100 kilomters distance, and HF band between 2mhz and 15mhz for long distance communication, over 1000 kilometers.Ī fourth way is mainly used in areas without coverage ADS-B/ACARS: satellite communications between aircraft and space, then retransmission to earth. VHF radio is used by pilots, takeoff, flight and landing in obtaining authorizations and information for the flight. This is the historical means of communication, still widely used, unencrypted and very easy listening. – VHF and HF radio system, used for oral communication by radio between the pilot of an aircraft and a ground station.
– ADS- B radio system for Automatic Dependent Surveillance Broadcast, a cooperative monitoring traffic.Īircraft equipped with ADS- B determines its position by GPS satellite positioning system and periodically sends its position to ground stations (control tower) and other aircraft operating in the area. The frequency range used is 1090MHz. VHF channel used since the 1970s is now supported by a SATCOM satellite link in shadows region such as the oceanic region.ĪCARS system is also equipped with a communications system on HF bands, to listening from a land over thousands of kilometers. ACARS also provides operational and logistical communications. It enables automatic control of condition of the aircraft in flight by service center of the airline company to know the status of the flight before landing. – ACARS radio system for, Aircraft Communication Addressing and Reporting System, mediated by the crash MH370 is a monitoring and coded radio communications system between an aircraft and a ground station. Radiocommunication systems of an aircraftģ radio systems are mainly used for terrestrial communications and sending GPS information of an airplane : Surprisingly, radio technologies used for geolocation and tracking of aircraft are quite classic and easy to listen/decode, still nowadays.įrom a radio point of view with SDR USB stick receiver, it has never been so easy and inexpensive to receive, decode yourself, GPS positioning information sent in real time by aircraft passing near his position !Įquipment is for less than 20€, with a simple USB DVB-T, DAB TV receiver USB stick, you can begin to receive and decode RTL-SDR GPS info sent in ADS-B and ACARS by aircraft.
The Navy and Air Force are the major users of the aeronautical mobile (OR) bands. Nationally in the U.S., the use of the aeronautical mobile (OR) service bands is mainly for military operations that include controlling traffic routes and special military needs. Frequencies in the bands allocated exclusively to the (OR) service are nationally used primarily for the satisfaction of military aeronautical requirements. Aeronautical Mobile (OR) Service: An aeronautical mobile service intended for communications, including those relating to flight coordination, primarily outside national or international civil air routes.
